[Documentation] Updated the checkpatch parameters

Newer versions of checkpatch check for the use of camel case in the
code.  Although, dLeyna does not itself use camel case, it uses a lot
of glib structures and functions that do.  Therefore, this warning needs
to be disabled, otherwise you see a lot of spurious errors.
